Problems solved by technology

However, after the introduction of related technologies in China, frequent tripping of the device due to excessive current has occurred, resulting in the inability of the equipment to run smoothly
The reason is that most domestic refineries use a wide variety of crude oil with poor quality, resulting in complex components of catalytic cracking oil slurry and high content of solid particles, resulting in complex and changeable process conditions for electrostatic removal equipment

Embodiment 1

[0051] An electrostatic separation method for solid particles, comprising the following steps: heating the catalytic cracking oil slurry to 100°C, the heated oil slurry sequentially enters an AC pretreatment pipeline 111 with an electric field strength of 1000V / cm and an electric field strength of 1500V equipped with glass beads The solid particles are removed in the Y-type separation tank 110 of the straight-through deep treatment pipeline 112 of / cm. The oil slurry treated by the pretreatment pipeline 111 enters the waste material discharge pipeline 113 and accumulates in the waste material discharge pipeline 113, while the coalesced and grown solid particles in the treated oil slurry naturally settle along the pretreatment pipeline 111 to the waste material discharge In the pipeline 113, it is regularly discharged through the slag discharge port, and the purified oil slurry overflowing from the waste discharge pipeline 113 enters the advanced treatment pipeline 112 again. T...

Abstract

The embodiment of the invention provides a solid particle electrostatic separation device and method, and relates to the field of oil slurry purification treatment. The solid particle electrostatic separation device is suitable for removing solid particles in catalytic cracking oil slurry and comprises a Y-shaped separation tank and an electric field generation assembly, wherein the Y-shaped separation tank comprises a pretreatment pipeline, a deep treatment pipeline and a waste discharge pipeline, the pretreatment pipeline is communicated with the deep treatment pipeline, the waste discharge pipeline is simultaneously communicated with the pretreatment pipeline and the deep treatment pipeline and is Y-shaped, the pretreatment pipeline is not filled with an adsorption filler, the deep treatment pipeline is filled with an adsorption filler, and the electric field generation assembly comprises a first electrode for applying an electric field to the pretreatment pipeline and a second electrode for applying an electric field to the deep treatment pipeline. Solid particles can be removed step by step, coalesced and grown solid particles are prevented from backmixing in the flowing process and entering a deep treatment electric field, and the phenomenon of frequent tripping caused by too large current in the separation process is prevented.

Description

technical field [0001] The invention relates to the field of oil slurry purification treatment, in particular to an electrostatic separation device and method for solid particles. Background technique [0002] Catalytic cracking oil slurry is a by-product of the catalytic cracking (FCC) process, and its utilization is greatly limited due to its high content of solid particles. At present, most refineries sell catalytic cracking oil slurry as a blending component of heavy fuel oil, which reduces its utilization value. This is because the polycyclic aromatic hydrocarbons in FCC oil slurry can be used as high-quality raw materials for the production of many chemical products such as carbon black, needle coke, carbon fiber and extender oil, plastic plasticizers, and heavy traffic road asphalt additives. In addition, if the catalytic cracking oil slurry is used for combustion, the solid particles in it will easily cause many problems such as wear of the furnace burner and ash on...
